| Abstract | ||
| The marshes received large amount of water (42) billion m³/yr, (33) billion m³/y out of it is from the discharge of Tigris and Euphrates, which annually attain (78) billion m³/y. during 1970s in Iraq. Currently, as well as in future, it is difficult to achieve such a great amount of water due to the effect of the upstream basin developments projects (Turkey, Syria and Iran). This caused an apparent reduction in the rivers discharge in Iraq during (1990-1998) drop to 61 billion m³ and expects to be decreased to 45 billion m³ by the year 2020 as the demands reach 38 billion m³/yr. The present available water, which can restore the marshes, is about 16 billion m³/yr. This amount will be reduced in future because of reasons mentioned above. Therefore, Iraq should make a great effort to achieve fair agreement regarding the water quota among the countries of Tigris-Euphrates basin and apply an effective irrigation plan to reduce losses from 53% to 28%. This will also save about 14 billion m³/yr. Moreover, the drainage water should be controlled to an average of about 17 billion m³/yr. for reclamation and optimization use of the groundwater and Al-Tharthar reservoir (total storage capacity 77.6 billion m3). Such water strategy will promote water resources to satisfy future economic demands and supply water to the marshes. | ||
